I-Moorhen (Gallinula comeri) ingeyenyoni yamanzi yomndeni wabelusi.
Iyinyoni cishe engenamaphiko. Ngokokuqala ngqa ukuthi lolu hlobo luchazwe isazi semvelo uGeorge Kamer ngo-1888. Leli qiniso libonakala engxenyeni yesibili yegama lezinhlobo - i-comeri. UMoorhen waseGough Island uyilungu lohlobo lweGallinula futhi uyisihlobo esiseduze seqhwa, abahlanganiswe ngaso nezici zokuziphatha: ukudikiza okuqhubekayo kwekhanda nomsila.
Izimpawu zangaphandle ze-moorhen
UMoorhen waseGough Island uyinyoni enkulu futhi ende.
Inezimpaphe ezimnyama noma ezimnyama ze-matte ezinokumakwa okumhlophe. I-Undertail imhlophe, inemivimbo ezinhlangothini zombala ofanayo. Izimpiko zifushane futhi ziyindilinga. Imilenze mide futhi inamandla, ihlelelwe ukuhamba enhlabathini enodaka yogu. Uqhwaku luncane, lubomvu ngethiphu ephuzi. “Uqwembe” olubomvu ngokugqamile lumile ebunzini ngenhla komlomo. Ama-moor amancane awanalo uqwembe.
Izici zokuziphatha kwama-moorhen esiqhingini saseGough
AmaMoorhenes eGough Island awafihli kakhulu kunezinye izinhlobo zelusi. Zihlala kakhulu ezimileni ezinotshani obukhulu, kwesinye isikhathi zingacashile, zidla emanzini asogwini. AmaMoorhenes andiza ngokungabaza, kepha, uma kunesidingo, ayakwazi ukuthuthela ezindaweni ezinokudla okuningi. Benza konke ukunyakaza kwabo ebusuku.
IMoorhen eseGough Island cishe iyinyoni engakwazi ukundiza, ingakwazi "ukundiza" amamitha ambalwa, ishaye izimpiko zayo. Le ndlela yokuziphatha yenziwa mayelana nokuhlala eziqhingini. Imilenze ethuthukisiwe enezinzwane eziqinile zishintshelwa ukuhamba ezindaweni ezithambile, ezingalingani.
Ama-moorhenes aseGough Island ayizinyoni zezwe phakathi nenkathi yokuzalanisa futhi axoshe ngokuncintisana abancintisana nabo kude nendawo ekhethiwe. Ngaphandle kwenkathi yokwakha isidleke, bakha imihlambi emikhulu emanzini angajulile echibini ngohlaza oluminyene osebeni.
Ukudla okunomsoco eGough Island
I-Moorhen yase-Gough Island iyinhlobo yezinyoni ezithandayo. Uyadla:
- izingxenye zezitshalo
- ezingenamgogodla kanye nokubola,
- udla amaqanda ezinyoni.
Yize i-moorhen ingenazo ulwelwesi ezidladleni zayo, iyabhibhidla isikhathi eside, iqoqa ukudla ebusweni bamanzi. Ngasikhathi sinye, ugwedla ngezidladla zakhe futhi unqekuzisa ikhanda lakhe, efuna ukudla.
Indawo yokuhlala yaseGough Island
Ubulembu beGough Island benzeka eduze nogu, ezindaweni ezingamaxhaphozi naseziseduze nemifudlana, okuvame kakhulu kuFern Bush. Akuvamile ukuhlala ezingeni lezindawo zamadlelo we-hummocky. Igwema izindawo ezingamanzi ezimanzi. Uncamela ukuhlala ezindaweni ezinezihlahlana zotshani ezingadluli nezindawo ezincane.
I-Gough Island moorhen yasakazeka
UMoorhen waseGough Island unendawo yokuhlala elinganiselwe efaka iziqhingi ezimbili ezincane endaweni. Lezi zinhlobo zivamile eGough Island (eSaint Helena). Ngo-1956, inani elincane lezinyoni lakhululwa esiqhingini esiseduze saseTristan da Cunha (ngokusho kwemithombo ehlukahlukene, inani lezinyoni lingamabhangqa ayi-6-7).
Ubuningi bama-moorhen eGough Island
Ngo-1983, inani labantu baseMorhen Island lalingama-2000-3000 ngazimbili ngamakhilomitha ayi-10-12 endawo efanelekile. Inani labantu esiqhingini saseTristan da Cunha liyakhula, futhi manje izinyoni zisatshalaliswa kuso sonke isiqhingi, azikho kuphela ezindaweni ezinesembozo sotshani obuncane entshonalanga.
Inani labantu bomhlanga e-Ascension Islands, eSaint Helena naseTristan da Cunha Island balinganiselwa kubantu abavuthiwe abayi-8 500-13,000 ngokuya ngemininingwane edlule. Kodwa-ke, akucaci ukuthi zingafakwa yini izinyoni ezihlala esiqhingini saseTristana da Cunha kuhlu olubomvu lwe-IUCN, ngoba imigomo eyisisekelo yokuhlukaniswa kwabantu ayicabangeli iqiniso lokuthi laba bantu bamane bathuthelwa endaweni entsha, futhi abalibuyisanga inani lezinyoni endaweni yabo yangaphambilini.
Ukukhiqizwa kabusha kwama-moorhen esiqhingini saseGough
AmaMorhenes esiqhingi saseGough Island kusuka ngoSepthemba kuya kuMashi. Ukuphakama kokuzala kuphakathi kuka-Okthoba noDisemba. Kaningi izinyoni zihlala ngamaqembu amancane ama-2 - 4 ngazimbili endaweni eyodwa. Kulokhu, izidleke zitholakala eduze kwamamitha angama-70-80 ukusuka komunye nomunye. Insikazi izalela amaqanda ayi-2-5.
AmaMoorhenes abeka izidleke zawo ezihlahleni ezihlahleni ezakhiwe izingxenye ezifile zezitshalo noma hhayi kude namanzi esihlahleni esijiyile.
Isakhiwo sakudala esenziwe ngeziqu zomhlanga namaqabunga. Amachwane azimela ngokuzimela futhi engozini encane empilweni agxume aphume esidlekeni. Kepha sebethulile, bakhuphukela esidlekeni. Bashiya indawo yokukhosela ngenyanga.
Lapho zisongelwa, izinyoni ezindala zikhombisa ukwenza okuphazamisayo: inyoni ifulathela futhi ikhombisa umsila ophakanyisiwe, ovulekile, unyakazise umzimba wonke. Isililo sama-moorhen nge-alamu sizwakala singenanhlonipho "ikhekhe-ikhekhe". Izinyoni zinikeza isignali ephansi kangako lapho zihola amantshontsho, kanti amaphuphu alandela abazali bawo. Zilele ngemuva komhlambi, zikhukhumala ngokuhaha, futhi izinyoni ezindala ziwathola masinyane amaphuphu alahlekile.
Izizathu zokwehla kwenani lama-moorhen eGough
Izizathu eziyinhloko zokwehla kwesibalo kukholakala ukuthi kwakudalwa amagundane amnyama (Rattus rattus), ayehlala esiqhingini, kanye namakati nezingulube zasendle, aqothula amaqanda namachwane ezinyoni ezindala. Ukucekelwa phansi kwendawo yokuhlala nokuzingelwa kwabantu besiqhingi nakho kwaholela ekwehleni kwenani lomhlanga.
Izindlela Zokulondolozwa Ezisebenza kuGeed Island Reed
UTristan da Cunha ubelokhu eqhuba uhlelo lokuqeda ikati kusukela ngo-1970 ukuvikela umoba eGough Island. IGough Island iyindawo yokulondolozwa kwemvelo nendawo eyiGugu Lomhlaba futhi iyindawo engenazo izindawo zokuhlala ezisemadolobheni.
Ngemuva kocwaningo olwenziwa ngo-2006, amagundane ayiswa eTristan da Cunha naseGough, okwabhubhisa amaphuphu kanye namaqanda e-moorhen.
Ososayensi bakulesi siqhingi bacwaninga ngomthelela wamalulwane ahlala emihumeni nasemigodini yodaka ezinombolweni zezinhlobo ezimbili zezinyoni (kubandakanya iGough Island moorhen) futhi basebenzisa ubuthi obungafanele.
Luhlaka lwekusebenta lwekucedza emagundvwane eGough lwalungiswa nga-2010, lwachaza luhlelo lwemsebenti kanye nesikhatsi sekucedza, lokwakhela etifundvweni letitfolwe kweminye imiklamo kucedza tinhlobo letingafuneki. Ngasikhathi sinye, kuyadingeka ukuthatha izinyathelo ezanele ukunciphisa umthelela ongaba khona wobuthi besibili ovela kumorhen, othatha izidumbu zamagundane afile futhi nawo ungafakwa ubuthi. Kufanele kuncishiswe ubungozi bokuletha izitshalo nezilwane ezingavamile, ikakhulukazi ukwethulwa kwezilwane ezincelisayo eGough Island.
Ukulawula isimo sezinhlobo, yenza ukuqapha ngezikhathi ezithile zeminyaka engu-5-10.
